  • Standard corporate income tax rate — 30% percent (of taxable income, in force since 1 April 2023 (it was 24% from 1 January 2020, and 28% before that). Apply to taxable income computed under the Inland Revenue Act No. 24 of 2017.) (Inland Revenue Act No. 24 of 2017)

3.2 Concessionary rate — 15% (remitted foreign currency)

  • Concessionary rate on remitted foreign-currency income/services — 15% percent (applies to qualifying foreign-currency-source income and services remitted to Sri Lanka through a bank. Require evidence of the foreign-currency source and the banking-channel remittance before applying.)

3.3 Higher rate — 45% (betting/gaming, liquor, tobacco)

  • Higher rate on betting/gaming and liquor/tobacco — 45% percent (applies to income from a business consisting of: betting and gaming; or manufacture and sale, or import and sale, of any liquor or tobacco product. Raised from 40% effective 1 April 2025 (Act No. 02 of 2025). The same 45% flat rate applies to individuals carrying on such business income.) (Act No. 02 of 2025)
  • Export of liquor/tobacco products — 30% percent (The export of liquor or tobacco products is taxed at the 30% normal rate, not 45%.)

  • Losses, depreciation, allowances. Computed under the IRA (Second/Fourth Schedules) — detailed loss carry-forward and capital-allowance rules are NOT asserted here; VERIFY against the IRA.

  • SSCL interaction. SSCL (2.5% on liable turnover) is a separate levy — see sri-lanka-sscl.

  • Capital gains on realisation of investment assets — 10% percent (flat rate for resident and non-resident; separate from business income. Company-specific characterisation (business asset vs investment asset) — VERIFY with the practitioner.)

Section 5 — Worked examples

5.1 Standard company

Taxable income LKR 50,000,000 → CIT = 30% × 50,000,000 = LKR 15,000,000.

5.2 Liquor manufacturer (domestic)

Taxable income LKR 50,000,000 from domestic liquor manufacture/sale → CIT = 45% × 50,000,000 = LKR 22,500,000. (If the same income were from export of the product, the rate would be 30%.)

5.3 IT services exporter, forex remitted through a bank

Qualifying remitted foreign-currency services income LKR 50,000,000 → CIT = 15% × 50,000,000 = LKR 7,500,000, provided the banking-channel remittance is evidenced.

  • Statement of Estimated Tax Payable (SET): under IRA s.91; YA 2025/26 due 15 August 2025.

Prohibitions

  • NEVER apply the 24% or 28% historical rate to YA 2025/26 — the standard rate is 30%.
  • NEVER apply the 15% concession without banking-channel forex-remittance evidence.
  • NEVER use the old 40% rate for betting/gaming/liquor/tobacco for periods from 1 April 2025 — it is 45%.
  • NEVER assert an SME/sector concession this skill flags as VERIFY.
  • NEVER file or instruct filing — produce a working paper for practitioner review.
